What is the ‘Castle doctrine’ in Law?

Also known as the castle law or the defense of habitation law, this refers to a doctrine in the common law tradition which states that a person who acts in self defence against an intruder into his personal property has the right to legal immunity for his actions.

A person who is defending his home against an intruder can use deadly force to protect himself and still be exonerated for his actions under the law.

The defendant employing the castle doctrine will have to justify his action with sufficient evidence and also explain the use of deadly force as an appropriate and reasonable response to the particular threat that was facing him.
